STOVEPIPE-LOCKING. DEVICE.,

` @aplicasion filed September 12, 192,2.' Serial No. 587,755..

T 0 all 'whom it may concern:

Be it known that I, JEFFERSON D. KING, a citizen of the United States,residing at Hendersonville, in the county of Henderson and State ofNorth Carolina, have invented certain new and useful Improvements in aStovepipe-Locking Device, of which the following is a specification.

My invention relates to improvements in stove pipe locking devices.

An object oit' my invention is to provide a stove pipe locking devicethat is so constructed that no rivets are used.

A. further object of my 'invention is to provide a stove pipe lockingdevice that is intended to take the place of riveting joints and that isso constructed that the sections may easily be taken apart for storagewithout any damage to the pipe and stove.

A still further object of my invention is to provide a stove-pipelocking device whereby it is impossible for the sections to slip looseor fall apart when in use.

A still further object of my invention is to provide a stovepipelockingdevice that .is strong, durable, simple and inexpensive inconstruction and that is well adapted to the use for which it isdesigned.

In the drawings, wherein like numerals are employed to designate likeparts throughout the same,

Figure l is van elevation of the apparatus embodying my invention, and

Figure 2 is a longitudinal section taken through the ksame.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 5 designates a sectionor length of pipe. In Fig. 2 of the drawings it will clearly be seenthat the section 5 is provided near one end with a raised portion 6,which may be called a substantially V-shaped flange. The raised portion6 is provided with a straight surface 7 which is approximately at rightangles with the length of pipe 5 and a beveled face 8 which terminatesin the short sleeve 9.

The numeral 10 likewise designates a section of pipe which is providedwith the resilient tongues 11 at one end. The sleeve 9 is adapted to beinserted in the end of the pipe 5, and the resilient tongues 1l areadapted to be bent down over the beveled face 8 as is clearly shown inFig. 2 of the drawings, the ends of said tongues being bent down overthe straight Jface 7 thus forming a permanent locking means. rlhetongues ll are vpreferably pointed as is clearly shown in Fig. 1 oit'the drawings. By reason oi. the sleeve 9 extending a slight distanceinto the pipe section 10, the joint will not be free to leak.

In use, each section of pipe should be provided with a joint, that isone end should be provided with the raised portion 6, and the oppositeend should be provided with the tongues 11. The end which has thelraised portion 6 as is illustrated on the end of pipe 5 in Fig. 2 of thedrawings, should be inserted in the end of the pipe section l() which isprovided with the tongues 11. The pipe 5 should be inserted as far aspossible in the pipe 10 and the tongues 1l should be bent down tocontact with the beveled face 8 and then bent over the end thereof so asto abut against the flat surface 7. It will thus be seen that a surelocking means is devised that may be easily disconnected when it isdesired, that will not ordinarily come apart. This device is eX tremelyeflicient in use, in view of the fact that there are no bolts or rivetsto become rusted thereby causing trouble when it is desired todisconnect the sections of pipe.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred embodiment of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of my invention or thescope orP the subjoined claims. f

I-Iaving thus fully described my invention what I claim is l. A pipecoupling comprising a pair of pipe sections, one section having anannular bead struck out therefrom defining an abrupt shoulder disposedat right angles to the longitudinal axis of the sections and an inclinedguide surface leading to the shoulder, and the other section having aplurality of right angularly disposed tongues for engagement with theabrupt shoulder of the bead.

2. A pipe for couplings comprising a pair of pipe sections, one sectionhaving an annular bead struck out therefrom adjacent to one end thereoildening an abrupt shoulder disposed at right angles to the longitudinalaxis of the sections and an inclined guide surface leading to theshoulder from the mentioned end of the section and the flange engagingthe inclined guide surface 10 other pipe section receiving the end ofthe of the bead;

lirst mentioned section having the bead, In testimony whereof I aix mysignature a flared lange formed on the end of the last in presence oftwo Witnesses.

mentioned section receiving the mentioned end of the first mentionedsection, and a JEFFERSON D KING' Vplurality of right angularly disposed'Witnessesz tongues formed on the flange for engaging FRANK A. EWBANK,the abrupt shoulder of the bead, the flared H. H. EWBANK.
